PURPOSE: To carry out ventilation in a subsidary room in a ship easily, by supplying air to be used for air-conditioning to the cabins of a ship so that the indoor pressure becomes higher than the atmospheric pressure and by exhausting the air in the subsidary room to the outer side of the ship by using the air leakaging from the cabins to the subsidary room under the atmospheric pressure.
CONSTITUTION: There are a number of partitioned cabins 1 in a ship and mutually adjacent subsidary rooms 2, are partitioned in each cabin 1. The temperature controlled air supplied from an air-conditioning device 9 is delivered to the cabin via an air conditioning duct 3 and an ejection hole 4 to maintain the optimum room temperature. In this case, each subsidary room 2 is provided with an exhausting duct 7 respectively communicating with the outside of the ship, and a plate 8 is mounted on the outer end of the exhausting duct in order to prevent invasion of the rainwater or the like. Furtheremore, the pressure in each of the cabins 1 is kept at a constant pressure which is a little higher than the atmospheric pressure. Accordingly, the ventilation in each of the subsidary rooms 2 is performed by forcing the air in each of cabins 1 to flow in each of subsidary rooms 2 staying under the atmospheric pressure via a gap formed at a door 5 or the like and thereby exhausting the air in each of the subsidary rooms 2 to the outside of the ship through the exhausting duct 7.
